Papers of Tony Lewis, statistician, relating to the Duckworth-Lewis scoring method for one-day cricket matches

Records relating to the development of the method, its adoption by cricket governing bodies and reaction to it in the press.

Tony Lewis was a lecturer in the faculty of computer studies and mathematics at the University of the West of England and later taught quantitative methods in management at Oxford Brookes University business school. He also served as chairman of the western branch of the Operational Research Society.

In 1993 he set a student project to evaluate the formula proposed by Dr Frank Duckworth, a consultant statistician and editor of the Royal Statistical Society's monthly magazine, in a paper entitled 'A fair result in foul weather: solving the one-day cricket enigma' (1992) (see1101/1/1-3). This led to him collaborating with Duckworth to develop an improved method for calculating the scores required to win one-day limited-overs cricket matches interrupted by bad weather. Following trials in 1997 in domestic cricket in England and Wales, England's tour of Zimbabwe and the ICC (International Cricket Council) Trophy in Kuala Lumpur, the Duckworth/Lewis method was adopted in 1999 by the ICC as the official rule to be used by all full and associate members for international and domestic matches.
